I am professor in physical oceanography, specializing in ocean renewable energy: characterizing the wave and tidal energy resource, understanding wave-tide interaction, optimizing grid integration of arrays of marine renewable energy devices, and quantifying the environmental impacts of extracting energy from the oceans. I am founder and course director of an MSc in Marine Renewable Energy, and committee member of the International Electrotechnical Commission (IEC), working on revising IEC Technical Specification 62600-201: Tidal Energy Resource Assessment and Characterization. I am a member of the editorial board of the Elsevier journal Renewable Energy, have written a textbook on marine energy "Fundamentals of Ocean Renewable Energy: Generating Electricity from the Sea", and am lead sediment scientist at FORCE (Fundy Ocean Research Center for Energy). I also have other shelf sea research interests, including palaeoceanography, sediment dynamics, and simulating the dispersal of marine organisms and microplastics.
